Study of the Wire Laser Additive Manufacturing (WLAM) Process Applied to a Low-Alloy Steel

Year: 2025

Type: article

Abstract: The Wire Laser Additive Manufacturing (WLAM) process enables the production of large-scale metal components. A thorough understanding of wire deposition regimes is crucial to minimizing internal and external defects, which are often responsible for the initiation of fatigue cracks. This work aims to identify the optimal parameters for printing medium- and large-scale structures using low-alloy steel. Using an instrumented WLAM experimental setup, an initial study is conducted to determine a stability window and to identify different bead geometries. A second study will focus on the quantification and analysis of internal defects observed during the printing of three-dimensional structures, by exploring various parameter sets within the stable deposition regime.
